Claude Shannon

Claude Elwood Shannon (April 30, 1916 – February 24, 2001) was an American polymath who was a mathematician, electrical engineer, computer scientist, cryptographer and inventor known as the "father of information theory" and the man who laid the foundations of the Information Age. Shannon was the first to describe the use of Boolean algebra—essential to all digital electronic circuits—and helped found the field of artificial intelligence. The roboticist Rodney Brooks declared Shannon the 20th century engineer who contributed the most to 21st century technologies, and the mathematician Solomon W. Golomb described his intellectual achievement as "one of the greatest of the twentieth century". At the University of Michigan, Shannon dual-degreed, graduating with a Bachelor of Science in electrical engineering and another in mathematics, both in 1936. As a 21-year-old master's degree student in electrical engineering at MIT, his 1937 thesis, "A Symbolic Analysis of Relay and Switching Circuits", demonstrated that electrical applications of Boolean algebra could construct any logical numerical relationship, thereby establishing the theory behind digital computing and digital circuits. Called by some the most important master's thesis of all time, it is the "birth certificate of the digital revolution", and started him in a lifetime of work that led him to win a Kyoto Prize in 1985. He graduated from MIT in 1940 with a PhD in mathematics; his thesis focusing on genetics contained important results, while initially going unpublished. Shannon contributed to the field of cryptanalysis for national defense of the United States during World War II, including his fundamental work on codebreaking and secure telecommunications, writing a paper which is considered one of the foundational pieces of modern cryptography, with his work described as "a turning point, and marked the closure of classical cryptography and the beginning of modern cryptography". His work was foundational for symmetric-key cryptography, including the work of Horst Feistel, the Data Encryption Standard (DES), and the Advanced Encryption Standard (AES). As a result, Shannon has been called the "founding father of modern cryptography". His 1948 paper "A Mathematical Theory of Communication" laid the foundations for the field of information theory, referred to as a "blueprint for the digital era" by electrical engineer Robert G. Gallager and "the Magna Carta of the Information Age" by Scientific American. Golomb compared Shannon's influence on the digital age to that which "the inventor of the alphabet has had on literature". Shannon is also regarded as the most important post-1948 contributor to the theory. Advancements across multiple scientific disciplines utilized Shannon's theory—including the invention of the compact disc, the development of the Internet, the commercialization of mobile telephony, and the understanding of black holes. He formally introduced the term "bit", and was a co-inventor of both pulse-code modulation and the first wearable computer. He also invented the signal-flow graph. Shannon joined the Central Intelligence Agency's Special Cryptologic Advisory Group in 1951. From 1956 to 1978, he was a professor at MIT. He also made numerous contributions to the field of artificial intelligence, including co-organizing the 1956 Dartmouth workshop, considered to be the discipline's founding event, and papers on the programming of chess computers. His Theseus machine was the first electrical device to learn by trial and error, being one of the first examples of artificial intelligence.

• I got a private lesson on Claude Cowork & Claude Code - YouTube

  Claude Cowwork is here and if you understand how to use it, you're going to be able to outperform 99% of people on this planet. It is an easy way for you to use Claude Code. You might have heard of Claude Code. It's gone viral. But the problem is it feels technical. You have to go into the terminal and it's not fun for a lot of beginners. So Claude has come up with co-work and it's a [music] brand new product that harnesses the power of Claude code in a UI that is simple that anyone could use that your dad can use, your mom could use. Hey, even you can use. So in this episode I brought on Boris, the maker of this product. I'm so excited that he shows you the best practices for how to use Claude Co-work and at the end how he sets up his Claude code to get the most out of it. You're going [...] Uh there's a few different tabs in the desktop app. So there's the chat, that's the default, there's co-work, that's the new one, and there's code, and that's just quad code. Um, co-work under the hood, it's actually just quad code. And so, you know, the agent that makes quad code awesome, we call it the quad agent. It's also available as the quad agent SDK. So you can use it programmatically. You can, you know, all sorts of companies build all sorts of cool things on top of it. We actually use that same exact SDK directly in co-work. Um, so it's like, you know, it's pretty cool. just kind of one layer across everything. We have the best agent, have the best agentic model, might as well use it. And so what I'll do is just to kind of show how how to use this thing. And you know, like when [...] the most out of both uh co-work and claude code. Everyone's thinking about it and everyone's trying to especially on this podcast, you know, the startup ideas podcast, you have millions of people who are trying to figure out how I can be more productive and how I can build businesses around some of these things. So, thank you. Thank you for the time. Um, I'll include links on where to follow Boris. He doesn't tweet a lot, but when he tweets, it's it's worth paying attention to. And I just have I want to leave with one thing just because my audience would kill me if I didn't ask this. So, as you know, Boris, I'm from French Canada, and we speak French, obviously, in French Canada, and I call Claude Clo. Am I the only one? [laughter] [clears throat] Oh man, you're probably not the only one.

  So, if you weren't living under rock over the past week, you probably heard of Claude Co-work. In summary, it's Chat GPT with the ability to remote control your computer and your browser. And when you give it a task instead of just doing it, it creates elaborate plan and then follows it step by step. We spent a week looking at different things you can do with this powerful tool. And in this video, we bring them all together. I show you what works, I show you what doesn't, and I give you some tips and tricks along the way. If you want to learn more about the details of co-work and how it relates to other products in AI space, I created a separate video on that on release. I'll link that below, but this video is going to be all about different ways you can actually put this to work. Let's [...] multiple tasks in parallel inside of Cowwork. And it came up with this. So, here I'm viewing the entire presentation in PowerPoint. Look at that. It's pretty good. Matter of fact, this would be a great way for me to walk through the video. I might even start using this on every video. If I have a video research or an outline, heck, why not just turn it into a slide deck, which then I can keep on my screen or second screen while I'm presenting. And again, it's not to say that AI could not create slide decks before. It's just the ability for it to go into my notion where it sits by itself and to work for 10 minutes independently and create something of this quality level. That's the difference. It's the ease of use of bringing these tools together and it just works. So I thought about this. [...] deeper. So, let's look at the next use case that you can make happen with cloth co-work. And this one links to the first task, but many people don't think of this. It's renaming images inside of those folders. So, let me just do that. And clot co-work, which by the way, now is available to all pro subscribers, too. That's the $20 plan a week ago when I created the other video. It was only the more expensive ones. And also, if you haven't seen that other video, this thing is only available on the Mac app for desktop now. Windows app coming soon. It always just releases on Mac first. Let's do this now. So, here in the co-work tab on my Mac app, I'll just say new tab. And I say name all of the screenshots in my downloads based on what they are. And I just hit go. And that's literally it.

• The 6 AM Dispatch: How I Use Claude Cowork to Run Five ...

  --- ## The Setup: Chat, Cowork, and Folders If you’re new to Claude’s ecosystem, it helps to understand the three interfaces Anthropic now offers. The browser-based chat is familiar: conversational, ephemeral, useful for quick queries. Claude Code is the power-user version with command line access, full agentic capabilities, and GitHub integration. Claude Cowork sits between them. If you’re interested in Claude Code specifically, In the Weeds by Hannah Steinberg is shaping up to be a really nice series on how to use it for non-technical users (like myself). [...] The key insight, and the thing that tripped me up initially, is that Cowork is fundamentally folder-based. You select a directory, and Claude operates within it: reading files, creating documents, organizing content. This sounds minor until you realize it means you can point Claude at your Downloads folder and ask it to categorize three months of accumulated chaos. Or at a project folder and ask it to draft a presentation from the materials inside. I reorganized my Downloads folder into a structure that supports this workflow: an “Active Work” folder, a “Today’s Work” subfolder, and category-specific directories. The architecture matters less than the principle: give Claude a clear context to work within. [...] ## Cost and Adoption Considerations I use Claude Max (it’s the only way to access Cowork) with Opus 4.5 enabled. The cost is not trivial— about $200/month. I personally believe the productivity gains justify the investment, and the morning hours I’m reclaiming are being spent on work that matters to me.

• Anthropic's new “Claude CoWork” sparks sell-off in ...

  Go to AI\_Agents r/AI\_Agents • Português (Brasil)Deutschไทย # Anthropic’s new “Claude CoWork” sparks sell-off in software & legal tech stocks — overreaction or real disruption? Anthropic just launched a new AI tool called Claude CoWork, and the market reaction was… brutal. Following the announcement, software, legal-tech, and professional services stocks saw a noticeable sell-off. The reason? Claude CoWork is being positioned as capable of automating high-value legal tasks like contract review, summarization, and structured analysis work that many firms still bill humans for. [...] According to analysts and traders, the tool itself wasn’t the only reason for the market dip. But it landed at a sensitive moment, amplifying existing fears that AI is starting to directly threaten business models built around expensive human expertise. What makes this different from previous AI hype: This isn’t marketing copy or customer support automation It targets legal and professional workflows, where margins are high It signals a shift from “AI assists humans” to “AI replaces chunks of billable work” Investors seem to be asking a hard question: If AI can do this reliably, what happens to firms whose value depends on time-based billing and proprietary expertise? So I’m curious what this sub thinks:
